Abstract

An interactive digital image processing workstation has been developed for oceanographic, metorological, geophysical applications (Fig 1.). The turn-key system provides the capability to process imagery from commonly used ocean observation spacecraft, in conjunction with in situ data sets. The system is based on the Hewlett-Packard 9000, a high-performance 32-bit processor (CPU), with a direct address range of 500 Megabytes. The Metheus Omega series of display controllers are used to drive the color CRT display. The controller memory may be configured to hold up to 1280x1024x32-bit images. The workstation provides the Global Applications Executive, which standardizes the link between the user and applications programs under the UNIX operating system. The user can operate the system in three modes. In the menu mode, the user is asked to make a selection from a list of menus and applications. In the command mode, the user communicates with the system via simple English-like commands. Finally, in tutor mode, the user is prompted for all parameters which must be supplied to a program. The applications software includes programs to perform geometric correction, earth location, and registration of remotely sensed data. These programs handle imagery from the Advanced Very High Resolution Radiometer (AVHRR), the Coastal Zone Color Scanner (CZCS), the Multispectral Scanner (MSS), the Scanning Multichannel Microwave Radiometer (SMMR), and the Visual and Infrared Spin Scan Radiometer (VISSR). Other programs permit displaying monochrome and true-color images. Line graphics, such as contoured data can be overlayed onto the displayed image in different colors. Interactive manipulation of these images is possible via a digital tablet provided. Interactive functions include panning, histogram normalization and pseudocolor manipulation.
